Comparison of Two Argentine Registries on Myocardial Infarction: the 2011 SCAR Registry and the 2015 AR GEN -IA M-ST Registry

Background: The aim of this study was to compare patients with ST-segment elevation myocardial infarction (STEMI) included incenters participating of two registries in Argentina.Methods: STEMI patients included in the 54 centers participating in the SCAR (2011) registry and in the ARGEN-IAM-ST (2015)registry were compared.Results: A total of 676 STEMI patients were analyzed: 222 in the SCAR registry and 454 in the ARGEN-IAM-ST registry. There wereno significant differences in age and sex. The use of fibrinolytic agents was significantly lower and the use of primary percutaneouscoronary intervention was significantly increased. The incidence of cardiogenic shock was 50% lower. There were no differences inmortality and reinfarction during hospitalization.Conclusions: The indication of primary percutaneous coronary intervention increased and the use of fibrinolytic agents decreased.Cardiogenic shock decreased significantly in the last 5 years without significant changes in in-hospital mortality.
